SWR global error handling doesn't catch all error

[vikyw89]

Bug report

as per doc here, the error handler should catch all error for global error handling purpose https://swr.vercel.app/docs/error-handling

<SWRConfig value={{
  onError: (error, key) => {
    if (error.status !== 403 && error.status !== 404) {
      // We can send the error to Sentry,
      // or show a notification UI.
    }
  }
}}>
  <MyApp />
</SWRConfig>

But it doesn't register error from:

• useSWRMutation
• mutate
• useSWRImmutable (I'm not sure about this one yet)

Expected Behavior

it should catch all error for global error handling purpose, especially all async function error / fetchers

Repro Steps / Code Example

• set up useSWRImmutable, useSWRMutation, and throw error inside it
• check if the error is logged by <SWRConfigValue={{ onError }}>

Additional Context

SWR version. Add any other context about the problem here.

workaround for now, catch the error using middleware
